Sitting in his wheelchair, Lawrence was silent for a long while before he looked up at Richard and slowly said, "If you really want to know my secret, I might as well tell you.
Why do I know how to make clocks, firearms, and such? It's simple, all because of my ancestors.
My ancestor was a craftsman in the Black Spirit Empire many years ago, working in a very famous workshop. Too much time has passed for me to know the specifics, but one thing is certain: after the fall of the Black Spirit Empire and his death, he left my family a wealth of books and drawings.
These books and drawings were almost unintelligible to my family, but my grandfather understood them, and then he taught my father, who, in turn, taught me.
After my father died, I devoted myself to study and made more than my father had taught me, which is what you see in this room."
"Is that so," Richard narrowed his eyes.
